1 E6240 Overview
1.1 Introduction
This kit is designed for the evaluation and development of applications using the
QT60160/QT60240 IC. The kit includes an evaluation assembly (E6240 – see Figure 1), cables
and QmBtn software. Each E6240 assembly has a serial (USB) interface allowing connection to a
computer for control and data viewing via QmBtn computer software.
This unique IC allows designers to create controls for various applications such a s mobile phones,
remote controls and MP3 players, amongst others.
Refer also to the QT60160/QT60240 datasheet.
1.2 Contents of Kit
1 x E6240 assembly (fitted with a QT60240 IC)
1 x USB-computer cable
2 x sample QT60240 ICs
1 x CD-ROM containing QmBtn software version 3.29 or later, User Manual and other information

2 Setting Up and Using the E6240
2.1 Setting Up
To prepare the E6240 for use, proceed as follows:
1. Using the USB cable provided, connect the E6240 to the computer (see Figure 2). Both LEDs
on the E6240 light constantly to indicate that there is power to the assembly.
2. Install the QmBtn software; either method is acceptable:
a. Put the supplied CD in the CD drive of the computer. Copy the contents of the CD to the
computer. Double-click the QmBtn software to open it.
OR
b. Go to www.qprox.com
Software and then the qmbtn (version 3.28 or later) link for the E6240. A dialog box
appears asking if you want to run or save the file that you are about to download. Click
Run. This automatically downloads the QmBtn software.
If a dialog box appears saying “The publisher could not be verified. Are you sure you want
to run this software?” click Run.
3. QmBtn software is displayed on the computer monitor. One LED is extinguished and the other
flickers continuously to indicate that the software is communicating with the E6240. Refer to
Section 2.2 and Section 3 for information about using the E6240 and QmBtn.
, point to the Support tab and click Download Archive. Click

2.2 Using the E6240 Assembly
1. Place the E6240 assembly on a level surface.
2. Keeping clear of the E6240, click Recall All on the QmBtn software.
3. Touch any key area on the E6240. Every time a key area is touched the corresponding key
area on the QmBtn software turns blue for the duration of the touch.
4. If the QmBtn software is not detecting, or detection is sporadic, decrease the detection
threshold slightly (NTHR, Section 3.3.2, page 9).
5. Refer to Section 3.3.2, page 9 and Section 3.3.3, page 10 for details of which parameters you
can change.

3.1 Introduction
QmBtn software is used with the E6240 assembly. With this software you can send commands and
monitor signals in real time.
The program consists of three main areas:
•
the QmBtn dialog box (which opens when the program starts – see Figure 3, page 5)
•
the QmSettings dialog box (which has three tabs, Key Settings, Global Settings and
Logging – see Figure 5, page 9)
•
the QmGraph dialog box (which gives real-time signals for individual keys) – see Figure 8,
page11
3.2 QmBtn Dialog Box
3.2.1 Introduction
The QmBtn dialog box provides the ability to monitor the status of all keys and the overall device in
real time.
